[Q] Root Xperia Z1 4.4.2 without unlocking bootloader or flashing modified ftf's

Is there any way to root Xperia z1 on 4.4.2 - binary method, without having to unlock bootloader or flash any modified ftf's?

No, there is no easy one-click root method for now. You can wait until someone finds an exploit and develops an easy method, but we don't know when that will be.

Locked Bootloader

My Bootloader is not unlockable. Bootloader unlock allowed = no. As far as I know I can't change to yes and there is no aosp roms on locked Bootloader. So my question is what can I do with a locked Bootloader? Also if I root on locked Bootloader can I still receive updates from Sony via ota?

Looking there will help you, there is no way to unlock the bootloader if it says 'no' you can still root your phone by downgrading to kitkat 108 and using the EasyRootTool to root your phone and then Nuts dual recovery installer. You will still be able to get OTA updates however they will remove root, you would need a pre-rooted firmware to keep root.

Okay so if install the previous rooted. 242 ftf I'll have root even after otas? And say I installed a 4k mod or stereo speaker mod, could I still receive ota?

Any OTA update will remove root meaning it will not exist on your phone. Any update you use will need to be pre-rooted in order to keep root on your phone.

How to root Xperia Z4/Z3+? [Marshmallow]

I just received a Sony Xperia Z3+(E6533) on stock Marshmallow 6.0 and I've looked up how to root but only got ways to root while it's on Lollipop. Is there anyway for me to root on this software or downgrade from Marshmallow to Lollipop on this phone?

You can also root your phone while on MM. You can unlock the bootloader, flash a rootable kernel followed by a recovery and than flash the SuperSu zip. No problem.
But it is not recommended to do so, because you will loose the DRM keys/functionality when unlocking the bootloader. And once the keys are gone there is no way to get them back.
The better way is to downgrade to LP (e.g. .266), backup the DRM keys (TA Backup) and proceed with unlocking the bootloader and rooting the phone.
That's also the way I did yesterday, when I got the Z3+.
And of course you will have to read... a lot...

Thanks for the heads up , I've been trying to figure out ways for my specific model all morning and last night.
So to downgrade I'll just unlock the bootloader first then get a Lollipop firmware and flash using flash tool then do the other steps such as getting a rootable kernel and so on?

No, that is not what I wrote. Before unlocking the bootloader you will have to flash a LP firmware assumed that you want to backup the TA partition with the DRM keys first. This can only be done under LP.
I think you will have to read a little bit:

What are the issues if we loose Drm keys? Will it affect non DRM normal contents? Or will it altogether disable Netflix or any other apps using Drm or other encryption?

Why don't create a guide?
